Definitions

  • the present invention relates to fasteners which receive and grip a shaft that are applied by simple axial insertion over the shaft. More specifically it relates to spring nuts of very small or micro size that can apply a residual clamp load.
  • a fastener according to claim 1 has been devised which can be installed by applying an axial pressing force onto a round pin, square tab or other mating component.
  • the fastener includes spring arms formed by bent tabs which deflect when pressed onto and grip the pin or other mating component between jaws of the arms making them resistant to being pulled off. Downward facing fingers located around the periphery of the fastener flex when they come into contact with another portion of the mating component. This creates a residual clamp load between the fastener and the component.
  • the fastener can easily be removed using a tool similar to snap ring pliers or needle nose pliers. Two holes on opposite sides of the fastener allow the part to be squeezed and deformed into an oval shape. This action disengages the arms from the pin or mating component and allows the fastener to slide off without resistance.
  • the fastener of the invention comprises a unitary body composed of resilient material, said body having a planar top with a circular periphery.
  • a substantially rectangular opening through the center of the top has pairs of opposing short and long sides, the centerlines of which define minor and major axes of the fastener, respectively.
  • An opposing pair of resilient arms extend upwardly and inwardly extend from the planar top. Each arm is affixed to one of the short sides of the opening along the major axis.
  • a plurality of outwardly and downwardly extending resilient fingers are located on the periphery of the top.
  • the top has two through-holes, each located on an opposite side of the opening adjacent its longer sides along the minor axis.
  • the holes are adapted to receive the application of opposing inwardly directed forces whereby the fastener is distorted such that the arms spread apart.
  • Each of the arms has an arcuate jaw at its distal end and each of the fingers is tapered radially.
  • the entire fastener is preferably a unitary element composed of spring steel or stainless steel with the same thickness throughout.
  • the present fastener described above can be used in a variety of assemblies but in particular, it can be effectively used with a second member having a head and an elongate shank which extends from the head such as a pin.
  • the fastener is located about the shank such that the arms engage the shank and thereby a residual clamp load is applied to the head.
  • the fingers of the fastener are preferably equally spaced apart.
  • the top has two through-holes, each located on an opposite side of the rectangular opening through the top adjacent its longer sides along the minor axis.
  • the inward sides of the holes are adapted to receive the application of opposing inwardly directed forces whereby the fastener is distorted such that the arms spread apart so the fastener can be lifted from the pin.
  • the fastener can be a one-piece element composed of spring steel or stainless steel.
  • the ability to press the fastener into position with a single axial force simplifies assembly compared to using the threaded joint of a nut and a bolt. As opposed to other non-threaded assembly methods this fastener has the benefit of providing a clamp load between panels. The ability to easily remove the fastener is another benefit compared to typical attachment methods.
  • the fastener has a relatively planar top 14 and a rectangular central opening 12 having pairs of opposing long and short sides, the centerlines of which define major and minor axes of the fastener, respectively as explicitly depicted in Figure 3 .
  • the center of the fastener is defined by the intersection of the major and minor axes.
  • a pair of integral opposing resilient tabs form spring arms 11 which extend upwardly from each of the two shorter sides of the opening 12 along the major axis.
  • Each of the tabs may include an arcuate top end as seen here and in Figure 3 .
  • a plurality of resilient fingers 13 extend outwardly and downwardly from the periphery of the top surface 14.
  • the fingers 13 are tapered but can also be sharply pointed or configured in any particular way that best suits its specific application.
  • Two vertical holes 15 pass through the top surface 14 and are located adjacent the longer sides of the central opening 12 on the minor axis. The holes are adapted for receiving the tines of a tool, which upon application of a squeezing force applied to the top surface 14 move the opposing arms 11 farther apart by deformation of the fastener.
  • Figure 2 depicts a cross-section of a front view which shows the configuration of the upward facing tabs 11 that prevent the fastener from falling off or being pushed off of a mating component part such as the pin shown in Figure 4 .
  • the arms 11 are designed such that they will be forced open by a mating component without yielding during installation. This creates a spring attachment force acting upon the mating component such as the pin shown in Figure 4 .
  • the resultant angle of the bend of the arms 11 makes its retention to the mating component difficult to overcome because the arms 11 react with a greater grip force against pull-out forces due to their inward wedging action against the mating component. This action increases the force and static friction of the arms against the component.
  • FIG. 3 another major feature of the invention are the through-holes 15 in the top surface of the fastener.
  • the holes 15 provide a place where a tool can be inserted to apply an inward squeezing force.
  • Lines A-A and B-B represent the major and minor axes of the fastener, respectively.
  • the squeezing force acts towards the captured pin 17 along the minor axis B-B and distorts the shape of the entire fastener.
  • the fastener is thereby forced into an oval shape from its circular free state. This distortion forces the arms 11 to open from around the pin 17 allowing the fastener to disengage from the pin and to be removed upward.
  • FIG 4 we see a view of the fastener installed over a pin 17 having a head 19 and a shank 16.
  • the fingers 13 are compressed when the fastener is first pressed against the head 19.
  • the fingers 13 are constructed so that they bend without yielding, hence this leaves a resultant stress in the fastener that creates downward force acting against the pin head 19.
  • the arms 11 form gripping jaws 18 which engage the pin shank 17.
  • the free space between the jaws 18 is appropriately selected to be less than the diameter of the pin or the width of the engaged component.
  • the jaws 18 may have an arcuate profile to match the diameter of the pin shank to increase the contact area for greater grip.
  • the clamp load is maintained since the fastener is prevented from moving upward in the opposite direction by the upward facing arms 11 that grip the pin shank 16 at an acute angle.
  • This construction of the invention seen in Figure 4 can function like a nut and a bolt which can be used to clamp elements together between the head and the fingers of the fastener.
  • a panel can be captured between the fastener and pin head 19 and other panels or materials can be added and clamped together face-to-face.
  • the pin shank 16 shown here is smooth and unfeatured but may include other features such as circular ridges to increase the static friction characteristics of the shank. Also, the pin shank 16 may extend farther upward beyond the first fastener to engage other similar fasteners or other structures as the case may be. It will be apparent to those of skill in the art from this and the other illustrations that there are many possible uses and adaptations where the present fastener can be employed.
  • FIGs 5A and 5B depict before and after conditions of the fastener when squeezed as described above. Only the tips 21 of the removal tool are shown here for clarity. As the fastener is squeezed, the holes move closer together which deforms the fastener as described above and forces the arms 11 farther apart. These conditions of the fastener correspond to the application sequence of the tool 23 seen in figures 6 and 7 , respectively. This deformation of the fastener moves the tabs away from the captured pin 17, releasing the retention force. Once the arms 11 are no longer in contact with the pin, the fastener is free to slide off of the pin without resistance.
  • Figures 6 and 7 depict a tool that utilizes two protruding pins 21 attached to moveable tines 23 of a tool handle (not shown).
  • the pins fit into the through-holes of the fastener 10 to transmit a squeezing force to the inward sides of the holes as the tines are forced together as indicated by the arrows in Figure 7 .
  • the result is the release of the fastener from the captured component as described above with regard to Figures 5A and 5B .
  • the squeezing force also applies a grip on the fastener by the tool so the tool can lift the fastener from the pin.
  • the tool can have pointed tips to aid in alignment with the receiving holes.
  • Materials suitable for the composition of the above described push-on nut are those which have the main properties of high tensile strength and a high yield-to-tensile-strength ratio. Examples include 301 full hard stainless steel and 1095 spring steel.
  • the inventive nut is particularly suitable for micro assemblies where for example the nut would have a diameter of approximately 3 mm and a thickness of 0.13 mm..
